An advance payment to an engineering supplier is normal, because the maker must buy steel, make tooling and commit capacity. It is also your biggest exposure, so protect it by paying in stages against verified milestones, not in one lump on trust.
This article sets out the checks and structures that reduce the risk. For legal advice on a specific contract, speak to a lawyer in your country.
How large should the advance be?
Keep it as small as the maker's real needs. A fair advance covers raw material and the first stage of work. If a supplier asks for most of the value up front, ask why, and ask to see the cost it is covering.
Common practice is to split the payment into stages. Payment terms for machinery orders lists the usual structures.
What checks should come before you pay?
Before the first transfer, confirm the basics. Skipping them is the usual cause of losses:
- The supplier is a manufacturer with a real plant, not a trader. See how to tell a trader from a manufacturer.
- The legal name, registration and bank account all match, and the account is in the company's name.
- The factory has been audited or visited, ideally by someone acting for you.
- A written contract or proforma invoice states specification, price, delivery date and penalties.
How can payment be tied to progress?
Link each payment to evidence: material received, machining complete, assembly finished, factory test passed, and goods loaded. An independent inspector can verify each step and release you to pay.
Consider a bank guarantee for large advances, where the supplier's bank promises to repay if the maker does not deliver. A documentary letter of credit is another option, with its own cost and paperwork. Safest payment terms for machinery: LC or staged payments compares them.
Write the milestones into the proforma invoice or contract, with each payment amount tied to a named stage. For example, a first payment on order confirmation, a second when the main components are ready for inspection, and the balance against the inspection report and the shipping documents. The details depend on the order, so adapt them to the size of the risk.
What if something goes wrong?
Write down what happens on late delivery, wrong specification and non-delivery: the remedy, the refund route and the law that governs the contract. Keep every email, photograph and inspection report.
Pay only by bank transfer to the company account on the invoice. Be careful with last-minute changes of bank details, which are a known fraud pattern; confirm any change by phone with a number you already hold.
Keep the final payment as leverage. Hold back a balance until the goods are inspected, packed and loaded, and until the documents you need for import are in your hands. Do not release the last payment on a promise to send the documents later, because customs clearance depends on them.
If you are dealing with a supplier for the first time, start with a smaller order so that your exposure is limited while you learn how they work.
